hi rob
first i must say THANK YOU VERY MUCH for your offer .
YOUR GREAT.
about the misunderstanding , i think it's more my fault ,
so sorry . and if i offended you in anyway about this subject , sorry
again.
about you offer to adding features , it's very nice of you .as you
know maybe we have another solution to the software problem , but
i would still like to accept your offer , if you would still
like to make it , and i would perfectly understand if you won't
because we may have another option and you might use it for other
purposes.
how much time would it take to a normal c++ prgrammer to make
chane 1 ( music ) and change 2(digital filters ?
if you still agree , i would try to find a c++ guy to do this.
so thank you very very much , your great (again) .
sincely yaniv.
